Technology simplifies automotive infotainment networking

An efficient automotive infotainment networking solution has been announced by Microchip that supports all data types over a single cable. Intelligent Network Interface Controller networking (INICnet) technology is a synchronous, scalable solution that significantly simplifies building audio and infotainment systems, offering seamless implementation in vehicles that have Ethernet-oriented system architectures.

The addition of mobile services, cross-domain communication and autonomous driving applications to in-vehicle networking infotainment systems require a more flexible solution for transporting packet, stream and control content. Existing implementations are either costly and cumbersome, or too limited in bandwidth and packet data capabilities to support system updates and internetworking requirements.

As audio is a key infotainment feature in vehicles, INICnet technology provides full flexibility through supporting a variety of digital audio formats with multiple sources and sinks. INICnet technology also provides high-speed packet-data communications with support for file transfers, Over-The-Air (OTA) software updates and system diagnostics via standard Ethernet frames.

Thus, INICnet technology supports seamless integration of Internet Protocol (IP)-based system management and data communications, along with very efficient transport of stream data. INICnet technology does not require the development and licensing of additional protocols or software stacks, reducing development costs, effort and time.

INICnet technology provides a standardized solution that works with both Unshielded Twisted Pair (UTP) at 50Mbps and coaxial cable at 150Mbps. With low and deterministic latency, INICnet technology supports deployment of complex audio and acoustics applications. Integrated network management supports networks ranging from two to 50 nodes, as well as processor-less or slim modules where the node is remotely configured and managed. The solution’s Power over Data Line (PoDL) capability saves costs on power management for microphones and other slim modules. Nodes can be arranged in any order with the same result, and any node in the system can directly communicate with any other node in the system.

INICnet technology comes with Unified Centralized Network Stack (UNICENS), a free-of-charge network management software. UNICENS shortens development cycles, reduces software complexity and simplifies system verification for an infotainment system linked by INICnet technology. UNICENS easily coexists with IP-based system management, simplifying the application code by separating system management from resource management.

Additional INICnet technology tools include a network analyzer, a network configuration tool, as well as evaluation boards with various feature sets, all through Microchip’s K2L subsidiary.

INICnet technology 150 products are available today in volume production quantities. INICnet technology 50 UTP samples are available now and will be available in volume production in 2019.
